HCV NS5A and NS5B enhance expression of human ceramide glucosyltransferase gene

Induction of Intrahepatic HCV NS4B, NS5A and NS5B-Specific Cellular Immune Responses following Peripheral Immunization

Numerous studies have suggested that an effective Hepatitis C Virus (HCV) vaccine must induce strong cytotoxic and IFN-γ+ T cell responses targeting the non-structural region of the virus. Most importantly, these responses must be able to migrate into and remain functional within the liver, an organ known to cause T cell tolerance. Using three novel HCV DNA vaccines encoding non-structural prot...

Performance of NS3, NS5a AND NS5b Hepatitis C Virus (HCV) Antiviral Resistance Sequencing Assays

Anoxia and reoxygenation of human endothelial cells decrease ceramide glucosyltransferase expression and activates caspases.

Endothelial oxidative stress induces cellular activation and sometimes death. Endothelial death can occur via necrosis or apoptosis. Understanding the mechanisms involved in cellular activation and death may lead to therapeutics designed to increase death or preserve cellular function. In the present study, brief periods of anoxia (3 h) followed by varying lengths of reoxygenation (0-5 h) lead ...

CLONING AND EXPRESSION OF HUMAN IFNα2B GENE IN SACCHAROMYCES CEREVISIAE

Interferon is a protein secreted by eucaryotic cells following stimulation by viruses, bacteria, and many other immunogenes. Recent medical studies indicate that interferons have effective role in the treatment of virus infections, immunodeficiency and certain types of cancer such as hairy cell leukaemia (HCL). The aim of the present study is to apply yeast strain for secreting human IFNα2b fol...

Human Choline Kinase-α Promotes Hepatitis C Virus RNA Replication through Modulation of Membranous Viral Replication Complex Formation

UNLABELLED Hepatitis C virus (HCV) infection reorganizes cellular membranes to create an active viral replication site named the membranous web (MW). The role that human choline kinase-α (hCKα) plays in HCV replication remains elusive. Here, we first showed that hCKα activity, not the CDP-choline pathway, promoted viral RNA replication. Confocal microscopy and subcellular fractionation of HCV-i...
